Highly Efficient Catalysis of Sulfur Reduction Reaction: 3d10‐Based Catalysts

open access: yesAdvanced Science, EarlyView.
Taking Cu and Zn, two typical 3d10 metal elements, as an entry point, this paper reviews the application of Cu‐based materials, Zn‐based materials and their Cu‐Zn‐based materials in accelerating the sulfur reduction reaction of lithium‐sulfur batteries, which can effectively alleviate the three major problems faced by lithium‐sulfur battery cathodes ...

Direct Visualization of Surface Structure and Charge States of Ceria‐Supported Gold Catalysts Under Redox Conditions

open access: yesAdvanced Science, EarlyView.
In the characterization of supported metal catalysts, a crucial aim is to conduct nanoscale analysis of the surface structure and charge dynamics in reactive gases. This study uses high‐precision electron holography in gas environments to observe the charge states of Au nanoparticles (NPs) supported on CeO2 during redox cycles.

Meta‐Dispersive 3D Chromatic Confocal Measurement

open access: yesAdvanced Science, EarlyView.
A dispersive metalens (DML) combined with the chromatic confocal method is achieved for high‐precision 3D measurement in this study. This approach enables both high axial and lateral resolutions in compact optics. The development offers a promising route toward precise, miniaturized depth sensing for future applications in microstructure inspection and

Hyperspectral Fluorescence Imaging with a New Polarity‐Ultrasensitive Fluorescent Probe

open access: yesAdvanced Science, EarlyView.
Based on the critical role of the π‐spacer in determining wavelength sensitivity to microenvironmental polarity, a new fluorescent probe, Lipi‐PS is rationally developed, which exhibits the highest polarity‐sensitivity so far. Its integration with hyperspectral fluorescence imaging enables multiscale polarity mapping across cells, tissues, and ...
